Kyrgios entered the match having lost all four of his previous matches to Murray, three in grand slams last year.

But with Murray battling a leg injury, Kyrgios ran the two-time grand slam winner ragged during the clinical display.

“I actually did promise a couple of my friends that next time I played Andy, I was going to beat him,” Kyrgios said. “He’s in the prime of his career. He’s been playing some great tennis. Every time I’ve played him I haven’t played bad.

“He’s just a great player and today I knew what my game plan was going to be and how he was going to play.”

The tie between Australia Green and Great Britain was sent to a live mixed doubles after Daria Gavrilova failed to successfully serve for the win in her 6-7 (7-2), 6-2, 7-5 loss to Heather Watson

Gavrilova was up 5-3 in the third set, but the naturalised Australian lost the last four games in a match that lasted 165 minutes.

But Australia Green got there eventually, securing a 2-1 tie win after midnight with a 6-2, 6-7 (7-0), 11-9 (match tiebreak) win in the mixed doubles.

The result means Australia Green will reach Saturday’s final if they can beat France on Friday night.

“It was a lot of fun. That match tiebreak was one of my favourite tiebreaks I’ve ever played,” Kyrgios said.

Murray appeared troubled by a right thigh injury during his singles loss, but he played down the injury after the match.

“It was just the same thing as the other day,” Murray said. “I’m still moving fine around the court, it’s just a little bit sore. I’ll be fine. No problem.”

Kyrgios kept his cool for most of his singles contest against Murray, but he became engaged in a quick exchange of words with a member of the crowd while scores were locked up at 4-4 in the second set.

Kyrgios lost the game, but he saved a break point shortly after before going on to win the match in a tiebreak.

The world No. 30 said his breakthrough win over Murray would give him a huge dose of confidence heading into the Australian Open.
